A landscape view of a modern gas refinery.

Explore our applications

Tail gas treatment

Eastman AdapT solvents are formulated to maximize selectivity in tail gas treatment units beyond the performance associated with unformulated MDEA.

Syngas treatment

Eastman AdapT solvents are tailored for the removal of various contaminants in syngas and can meet stringent specifications.
Refinery gas treatment

Eastman AdapT solvents have a strong track record for hydrogen sulfide removal from sour gases in refinery streams.
Natural gas processing

Eastman AdapT technical experts can help customers select the right solvent for acid gas removal from natural gas.

Ammonia production

Eastman AdapT is used in natural gas-based ammonia production. Carbon monoxide and carbon dioxide are poisons for the ammonia synthesis catalyst and must be removed.
Acid gas enrichment

Eastman AdapT can help produce a gas that is well enriched in HS. Selective hydrogen sulfide removal minimizes pickup of carbon dioxide.

Tailoring formulations

 

Acid gas removal, also known as gas sweetening, involves eliminating sour components like H2S and CO2 from gas streams. The requirements for this process vary significantly based on the gas source and its intended use. While stringent specifications often apply to residual sulfur components, not all gas streams contain H2S or other sulfur species.

Amines enable efficient removal of acid gases

CO2 concentrations can range from zero to over 50%, and complete removal isn’t always necessary. Gas streams may also contain traces of organics like mercaptans or carbonyl sulfide. Amines efficiently remove acid gases while minimally absorbing inert components such as hydrocarbons, hydrogen and nitrogen.

However, the kinetics of that reaction vary depending on the type of amine and the nature of the acid gas component. By selecting the right amine(s) and optimizing plant design, the system can be tailored to specific gas compositions and applications. Eastman can assist in this process.
